In a laboratory, Nakisha mixes a sodium hydroxide solution with an indicator called phenolphthalein. When
combined, they create a pink solution. Nakisha wonders if mixing other solutions with phenolphthalein will also
create this pink color. How could Nakisha use the scientific inquiry process to determine whether mixing other
solutions with phenolphthalein will also create a pink color? Check all that apply.
by making qualitative observations about the sodium hydroxide and phenolphthalein in solution
by asking a classmate if sodium hydroxide turns pink when mixed with other solutions
by comparing the given solution to other familiar solutions containing phenolphthalein
by designing an experiment to test phenolphthalein with other solutions
by repeating the experiment at different temperatures

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent. true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight. a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
